Discovery Sessions to Understand Requirements
This was a repeat requirement from an old client who was to design the experience of a self check out kiosk with a product scanning/detection system. The technology combines the concept of self-service checkout with an added product scanning/detection system. The mechanism would be a self-service checkout counter – with the addition of a tray on which the user places the products to be scanned/detected and a camera that would check the products on the tray. Any errors with the scanning, placement of products would throw up an error on the self-checkout screen.
To get the requirements in place and get a better understanding of the system, I set up multiple discovery sessions with the client and stakeholders. Each session gave us clarity in understanding what needed to be done. The project had quick timelines and deliverables which is why we tried to gain as much possible from the sessions, making extensive notes, and ensuring we got clarifications as soon as possible.
Research, Scenarios and User Flows
A list of probable screens was shared with the client. Along with that, I worked on the first cut of wireframes for the flow. With the wireframes approved by the clients, I worked with our team and the client’s design team to come up with the screens for the kiosk. While designing the screens, we kept in mind the branding guidelines shared by the client. With multiple iterations, the final screens were shared with the development team. With a final UI review, all the deliverables were shared with the client.
